Earth-21798
Earth-21798 was created when Phil Coulson sold his soul to Mephisto and obtained the Pandemonium Cube, a demonic artifact capable of warping reality.[1]
The history of Earth-21798 is presumably similar to Earth-616's, but with several notable differences. Some of these include:
- The Squadron Supreme of America were the supreme superhero team of Earth instead of the Avengers as the Avengers were never formed
- Tony Stark never created the Iron Man Armor as he was never injured in a warzone
- Carol Danvers was a pilot and never became a superhero
- Captain America was never retrieved from the ice in the Arctic
- The Hulk was exiled to the Negative Zone after his first rampage
Blade the Vampire Hunter found himself on Earth-21798 without explanation and discovered the various differences between it and Earth-616. After talking with Nighthawk and with Odinson, Blade decided to do something about this by reassembling the Avengers, starting with Captain America.[2]
According to Nightbird, this reality had been destroyed.[3] This is likely when it got unmerged from Earth-616.[4]
